  New photochromic chemosensors for Hg2+ and F−

  摘要：

  Two new chemosensors (1a and 1b) based on photochromic dithienylcyclopentene were designed and synthesized, and their spectral behaviors toward various metal ions and anions were investigated in detail. Compounds show excellent optical properties and distinguish Hg2+ and F- in CH3CN. Job's plot reveals that the presence of Hg2+ induces the formation of a 1:1 complex between 1a or 1b and Hg2+. From the spectral responses and H-1 NMR analysis, the deprotonation of the thioamide protons is proposed to explain the sensing mechanism for 1a and 1b toward F. It is found that 1a and 1b exhibit ring-opening and ring-closing photoisomerization with UV-vis light irradiation. Furthermore, their photochromic properties can be modulated by Hg2+ and F- ions. Moreover, 1a and 1b in photostationary states become promising sensors for Hg2+ and F- with high selectivity. (C) 2010 Elsevier Ltd. All rights reserved.

  日期：——

  New unsymmetrical diarylethenes were synthesized and their photochromic and fluorescent properties are tailored by Cu2+ and CN− coordinations. A novel molecular logic keypad lock is constructed based on the fluorescence emission changes by the inputs of UV/visible irradiation, Cu2+ and CN−.

  合成了新的非对称二元乙烯，并通过 Cu2+ 和 CNâ 配位定制了它们的光致变色和荧光特性。根据紫外/可见光辐照、Cu2+ 和 CNâ 的输入对荧光发射的影响，构建了一种新型分子逻辑键盘锁。
